Abstract

Recent polarization transfer measurements of the ratio of elastic form factors GE/GMon the proton are not in agreement with the results of Rosenbluth-type experiments. A two photon exchange contribution to the elastic cross section is the leading theoretical candidate to explain the discrepancy. A definitive test of this theory is the direct comparison of e+p and e-p elastic scattering. A proposed measurement of this sort using a novel mixed e+e-lepton beam and the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab is described. Preliminary results from an engineering test run showing a clear signal of elastic e+p and e-p are presented.
